Therefore, the main relief valve removed, and did not find anything 1 phase hoist unusual , installation, fault persists after washing , then noticed wire rope hoist the car's main overflow remote pilot control , that is when the solenoid valve if the volume is too power- under the circumstances , can also cause the valve to open , causing the unloading . So, first unplug the plug , test failure persists. After the first principle in line with the easier , start with a constant power supply leads directly promote the solenoid valve , then found electric cable hoist the solenoid valve on the bright lights , but when you can not hear the normal operation of the solenoid valve 1 phase hoist, so the electromagnetic overall valve removed , and the disintegration of the original discovery of the return spring break solenoid valve , under the action of gravity core , pushing the valve stem , so that eventually led to winch commutation circuit without pressure . After replacing the spring , to eliminate the phenomenon of test failures . View Details

Brake in crane operation 1 phase hoist mechanism, rotating mechanism and 1 ton chain hoist mechanism, can make these institutions to the desired accurately and reliably stop position. If installed in the lifting mechanism, in addition to load in a state of brake role, also can adjust rate of descent.Brake according to the way of action points closed and open; According to the structure of the block type and belt type; According 1 ton electric hoist to the transmission points of mechanical drive, hydraulic drive and electric. In general, often closed double block block brake is more common in the crane. And manual hoist general friction ratchet type one-way brake, can brake under load, very convenient.Brake lifting equipment is one of the important parts, rival chain also is 1 phase hoist, its main function is to make the moving parts (mechanical) slow down, stop or keep the status, and other functions of a device View Details

1 phase hoistt problems solution

Abnormal noise when running: 1 phase hoist a lot of trouble, for example, the control of electrical appliances, motor and reducer, etc appeared fault, is often accompanied by abnormal noise, the 1 phase hoist noise of the position and height and don't have the difference, with the cause of the problem in different maintenance, want to listen to...
Abnormal noise when running: 1 phase hoist a lot of trouble, for example, the control of electrical appliances, motor and reducer, etc appeared fault, is often accompanied by abnormal noise, the 1 phase hoist noise of the position and height and don't have the difference, with the cause of the problem in different maintenance, want to listen to see more, can make use of, or according to the fault characteristics of noise, determine a sound position, looking for and repairs.
(1) the abnormal noise occurred in control circuit, a noise, 1 phase hoist is generally contactor failed (such as ac contactor contact discrepant poor contact, voltage grade, magnetic core, CARDS, etc.), to deal with fault contactor for maintenance, must be replaced when unable to repair, after processing, to eliminate the noise.
Abnormal noise, (2) motor, should immediately stop, check whether the motor is single-phase operation, or bearing damage, coupling axis is not straight, and the chamber 1 phase hoist, these will make the machine has abnormal noise, the noise of the different fault location and high and low and don't sound different, single phase operation, the motor from regular strong and weak "buzzing" sound. And bearing damaged, near the bearing and issued with "hitched - hitched" "buzzing" sound. And coupling axis is not timing, or motor slight sweep chamber, a 1 phase hoist, the motor is not associated with shrill voice. In a word, should according to different noise, the find out fault, item by item, inspection, to recover the normal performance of the motor, when the motor fault unprocessed, banning the use of the gourd.
(3) the abnormal noise from the gear reducer, gear reducer failure (such as reducer or lack of lubricating oil bearing, gear, wear or damage to the bearing damage, etc.), then should stop check, first determine reducer reducer or bearing before use if the lubricating oil, oil change regularly in use, such as no lubrication, according to the requirement reducer will not only produce high "buzzing" sound, gear and bearing excessive wear or damage.

Mini 1 phase 1 phase hoist with urgent stop switch and forcibly disconnected limit switch, ensure the safety of the use of household electric hoist; Degree of protection IP54, with thermal protection device, improve the service life of 1 phase hoist. In terms of hook, specially designed for the advanced double Settings, greatly increased the mini electric hoist lifting weight, user can choose according to their own requirements single hook, double or use driving using mini electric hoist. Mini electric hoist is a kind of new type electric hoist, it is widely used in machinery, electronics, automobile, shipbuilding, assemble the workpiece and the high and new technology industrial park, and other modern industrial production line, assembly line, assembly machine, logistics, transportation, etc. In the warehouse, dock, ingredients, hanging basket, and the work in a narrow working space, more can show its quality.

Use force more force when the electric hoist to pay more attention to the following aspects:
More than a force force electric hoist homework manipulate employee should no-load test inspection before working environment, more forces electric hoist device itself and spreader etc;
2 when the rest of homework do not allow the heavy weight suspended in the air, to prevent parts produce permanent deformation;
Force more force electric hoist empty hook should be hanging in the air, avoid empty hook to the ground, and make the wire rope too loose, arranged on the drum is not clean;
Do not allow to tilt the lifting heavy cargo and electric hoist as drag tool use, due to the inclined condole, suspension can make the gravity of the wire rope tension than lifting the goods;
Three more forces axial travelmotion electric hoist electric thoughts about 1.5 when the factory has been transferred to the cafe, it will follow in using damping ring wear and increase gradually, if discover the brake after heavy decline amount is larger, should check the brake adjustment, general adjustment has to be replaced after three brake ring, to ensure the safety in braking;
Four more forces electric hoist to often inspect the guide rope device on the drum, to ensure that the wire rope is pressed tightly wound roll on the drum and sequentially; Reducer in check on the height of the lubricating oil, according to delimit the oil change, and ensure that the quality of the lubricating oil is good.
